Donald Trump is bringing his presidential campaign this weekend to Washington and Oregon, states holding primaries later this month.

Trump will start off Friday night in a liberal bastion, holding a rally at the Lane County (Oregon) fairgrounds convention center in Eugene, not far from the University of Oregon campus.

He will move to a midday rally in Spokane on Saturday. A third event, in the conservative border town of Lynden, is slated to begin at 3 p.m.

The presumptive Republican presidential nominee was nearby before he entered politics. He presided at the groundbreaking for the Trump Towers hotel and apartment complex in downtown Vancouver.

Officials of the Canadian city, including Mayor Gregor Robertson, have called on the local developer to remove Trump's name from the newly completed building. A Mexican-born construction worker sneaked onto the roof recently and displayed the flag of Mexico.

In Lynden, Trump will be in the legislative district of state Sen. Doug Ericksen, a state co-chair of his presidential campaign. The town is about as solidly Republican as any place in Western Washington, voting the exact opposite of liberal Bellingham 20 miles to the south.

It also boasts the spacious Northwest Washington Fairgrounds, tentative site for the Trump rally.

The Trump visit takes place against a backdrop of unrest and division amidst ranks of the state's Republicans.

U.S. Senate candidate Chris Vance, a former Republican state chair, said Thursday that he cannot vote for Trump. Trump was denounced on Wednesday by 2012 Republican gubernatorial nominee Rob McKenna, and by state Sen. Steve Litzow, R-41.

Very conservative U.S. Rep. Cathy McMorris Rodgers, whose district includes Spokane and is a member of the House Republican leadership, is not yet ready to support The Donald.

McMorris Rodgers told the Spokesman-Review that she wants to have a "conversation" with Trump, to ask him to explain statements about women that she described as "hurtful" and "inappropriate."

Anti-Trump demonstrators are expected to turn out in force. Gov. Jay Inslee will headline a Friday news conference in Seattle, featuring leaders of the area's Hispanic community and a prominent Muslim.
